TPS3435: TPS3435JFMAFSDSER

Part Number: TPS3435

Tool/software:

We are developing a medical device and planning to adopt the TPS3435 series watchdog.
Key Specifications:

  1. Package Requirement: WSON (6-pin)
  2. Current Option: TPS3435JFMAFDSER (closest match but suboptimal).
  3. Issues with Current Option:
    • Watchdog Timeout (tWD)​: 50 seconds (too long).
    • Startup Delay (tSD)​: 10 seconds (exceeds needs).
  4. Desired Parameters:
    • Watchdog Timeout (tWD)​: 1–3 seconds (ideal range).
    • Startup Delay (tSD)​: 500 ms – 3 seconds.
      Question: Are there alternative WSON-6pin models meeting these timing requirements?
